As brain injury was often observed in instances of skull fracture, it was deduced that brain injury could also be predicted by linear acceleration.17 However, research has since suggested that the mechanisms of mTBI are more complex than can be described by linear acceleration alone, and that head rotation plays a large role in producing injury.19 Linear acceleration has been correlated to the development of transient intracranial pressure gradients resulting in focal injury, while rotational kinematics have been correlated to shearing of the brain tissue resulting in diffuse injury.19,20 Real-world head impacts involve both linear and rotational components, and metrics that include both are good predictors of concussion.35,44 As concussions are common in cyclist crashes,8 there is value in assessing a helmets ability to reduce risk of concussion in addition to the severe injury levels addressed by standards
So this turned out to be more involved and more expensive than usual
